Book Description
Until recently, conversion of hardwood stands on poor sites to white pine (Pinus strobus L.) was limited mostly to natural white pine reproduction released from a hardwood overstory, either by killing the hardwoods or by removing them through a timber sale. However, in our effort to increase the returns from poor sites in West Virginia (oak site index 45 to 60) we have been introducing white pine where advanced natural white pine is scarce or absent. The results of several conversion studies completed during the past 6 years and the results of pertinent research conducted elsewhere are summarized and reported here.

Book Description
S2The Universities of Maine, Massachusetts, and New Hampshire, in cooperation with the Northeastern Forest Experiment Station, initiated in 1959-60 a study of the effects of site and stocking on the growth of eastern white pine. The primary purposes of the study were to develop equations for: (1) predicting the volume increment per acre of pure, even-aged, white pine stands from observable characteristics of the stand, soil, and topography; and (2) predicting the increment of individual white pine trees related to characteristics of the tree, stand, and site. By 1965, measurements of stand growth and development for a 3-year period were available from nearly all field plots. A preliminary analysis revealed that one or more additional remeasurements should be taken before a final summary of the periodic growth of trees and stands is made. Nevertheless, useful and accurate relationships were developed between stand yield, or volumes per acre, and stand age, site, and stocking; and this information is presented in this paper. Yield tables based on the plot data from New Hampshire, using stand height in place of age and site index, have been published by Barrett and Allen (1966).S3.
